Session 2: Not exiting, rather than maximizing profits — USDJPY Ultimate capital management design (6 sessions total)

In the previous article, we introduced why USDJPY Ultimate chooses the “trending-following” path, the classic approach, and why the design centers not only on “entry conditions” but also on “conditions to not enter.”

This time, as a continuation, we will talk about settlement and risk management.

No matter how precise the entry conditions are, not every trade will be profitable. Therefore, when designing an EA, you need to consider not only “how to win” but also “how to behave when you lose.” USDJPY Ultimate adopts a design that manages risk at multiple levels, not only per trade but also on a daily and account basis.

Stop-loss should be aligned with the market, not fixed

Setting a fixed number of pips for stop-loss is simple and easy to understand, but it tends to be inflexible when market volatility changes. In a high-volatility market, a too-narrow stop-loss may be hit by short-term noise even if the trend itself is not broken, and in a low-volatility market, setting a wider stop-loss than necessary means you are tolerating a distance larger than the price movement warrants.

Therefore, USDJPY Ultimate adopts a design where the stop-loss width is not a fixed value but changes in accordance with the current market movement (ATR). In high-movement phases, SL width becomes wider; in low-movement phases, it becomes narrower.

Profit should be secured up to a fixed target while preserving unrealized gains before a reversal as much as possible

While the stop-loss side changes with the market, profit-taking is set with a fixed pips width as a target.

Then, when unrealized gains extend to a certain level, a trailing stop is activated. This mechanism trails the exit line in the direction of profit as unrealized gains increase, aiming to preserve accumulated gains even if the price reverses before reaching the target.

Fund management is not just about trading units

So far, we’ve explained risk management for a single trade. However, even if each loss is within tolerance, a prolonged mismatch with the market can cause losses to accumulate. Therefore, USDJPY Ultimate adopts a concept of risk management across different levels: “trading unit,” “daily,” and “account” levels.

However, this does not guarantee that losses are completely prevented. Sudden price movements, slippage, or network conditions may prevent settlements exactly at the set levels. It is designed to help limit loss growth as a risk-management tool.

The “winning logic” and the “losing-logic” are separate

When people think of EA, they focus on where to buy and where to sell—the entry logic. In reality, however, design cannot be completed there alone. USDJPY Ultimate designs the “logic to win” using SRSI, MA, ADX, and daily RSI, and a separate role for the “logic to manage losses” with ATR-driven SL, take-profit, trailing stop, daily loss cap, and account-wide drawdown management.

This is connected to the idea from the previous article of “designing not only to enter but also to avoid entering.” There is no absolute in the market. Therefore, it is important to predefine rules not only to increase winning opportunities but also to manage losses when they occur.

Next time, we will discuss why we publish parameters of this logic and the reasons behind it.
